Canyons Endurance Runs by UTMB®

Canyons Endurance Runs by UTMB takes place in Foresthill on April 23 and 24, 2027, on mountain trails and through forest. Four distances are offered as part of the UTMB World Series: 25K (15.5 miles, about 2,800 feet of climbing), 50K (31.1 miles, about 5,600 feet), 100K (62.1 miles, about 12,300 feet) and 100 miles (161 km, about 18,200 feet of climbing).

These are mountain ultras, so the vertical matters far more than the mileage on paper. The 25K is a realistic entry point if you already run trails; the 100K and 100-mile options demand a year of consistent training, long back-to-back weekends and a tested plan for eating, lighting and aid stations. Practice hiking the climbs efficiently, because on courses like these that is where the time is won.
